Definitions
- the invention relates to an unlocking mechanism for a vehicle seat, in particular for a motor vehicle seat, with the features of the preamble of the claim 1.
- vehicle seats are known whose backrests can swing forward after actuating an unlocking mechanism, to facilitate access to the fund.
- the backrests can be folded into table positions or the whole Vehicle seat from a seated position into a folded package position are transferred, each by actuating an unlocking mechanism.
- the invention is based on the problem of an unlocking mechanism at the beginning to improve the type mentioned. This object is achieved by an unlocking mechanism with the features of claim 1 and by one Vehicle seat with the features of claim 11 solved.
- Advantageous configurations are the subject of the subclaims.
- the Floor unlocking the seat part at least partially from the vehicle structure separates, with a single control different functions of the Vehicle seat can be triggered, which is a comfortable, simple, clear and safe operation guaranteed. If the vehicle seat has a package position has, this can be achieved by operating a single control element so that the invention is preferred for such vehicle seats, i.e. usually with front passenger seats and seats in the middle rows and rear rows, Applies, but is not limited to such.
- a common one Actuating element for the backrest release and the floor release offers a higher operating logic, since these two releases when transitioning to Package position to be actuated immediately one after the other, whereby the Time sequence preferably checked and controlled by suitable query means can be.
- the two movement options of the actuating element are for a defined handling preferably decoupled from each other, so that the backrest release and the floor release completely or largely independently of each other can be operated with the same actuator. It is an advantage if first the unlocked backrest must be folded down and in the case of a longitudinally movable Vehicle seat this in a defined longitudinal position, for example in the rearmost longitudinal position or in the design position must, before the floor release can be unlocked. Suitable for this Interrogation means, for example in the form of buttons and control curves be sure that the floor release is not in a sitting position or can be unlocked even when using the seat.
- the actuation of the backrest release and the floor release can, for example by waves, which occur only with one of the two movement options of the actuating element are in operative connection with one another, for example via levers which are arranged on the shafts in a rotationally fixed manner and which engage can and the relative position of the longitudinal position can be queried, wherein the actuating element is assigned to one of the two shafts.
- one of the two shafts is preferably within a tube or a connecting crossbar, which or which a component of the Structure of the seat part forms, this component then a radial opening for one has the lever that is as small as possible so as not to close the component too much weaknesses.
- the actuating element is designed as a movable, For example, rotatable, hand lever formed, which when moving the backrest release from a rest position in a first actuation direction triggers and when moving from the rest position into a second Actuating the floor release triggers, the latter function at backrest not folded is preferably locked.
- a rotatable training the two directions of actuation correspond to the two opposite directions of rotation.
- the decoupling of the two directions of rotation can be achieved by idle strokes
- Hand lever be realized, for example by slot-pin guides, so that the radial opening in the tube can be kept small.
- a vehicle seat 1 is designed and has a rear seat for a so-called van a seat part 2 detachably connected to the vehicle structure of the van and one around swiveling backrest 3.
- Two hinge fittings 5, their respective fitting lower parts 7 are attached to the structure of the seat part 2, wear with their respective fitting upper parts 9 the backrest structure of the backrest 3.
- the backrest 3 is arranged on the seat part 2 in the rear in the direction of travel.
- the seat part 2 is designed that its upper part including backrest 3 by a longitudinal adjuster known per se is displaceable and lockable in the longitudinal direction of the van.
- the articulated fittings 5 designed as latching fittings or as wobble fittings can be unlocked by means of a backrest release 11 in order - in the case of training as a locking fitting - adjust the inclination of the backrest 3 or around - in both cases - the backrest 3 about a backrest rotation axis 3 'towards the seat part 2 Valves.
- the backrest release 11 has a profiled, upper transmission shaft 13 on which within a horizontal and transverse to the direction of travel arranged, hollow connecting cross member 15 is rotatably mounted.
- the connecting crossbar 15 is welded on the end face to the respective lower fitting parts 7 and forms part of the load-bearing structure of the seat part 2.
- the upper Transmission shaft 13 carries in the area of each end rotatably an unlocking disc 17, which within a rotation in a manner not shown of the associated joint fitting 5 can be pivoted via an unlocking bolt 19 Actuates cam, which locks the pawl upper part 9 to open.
- a one-armed actuator Hand lever 20 rotatably arranged on the upper transmission shaft 13.
- the hand lever 20 is in one piece with the unlocking disk arranged on this side 17 trained.
- the upper transmission shaft 13 is rotated so that on both sides of the vehicle seat 1 the joint fittings 5 are unlocked at the same time.
- Various Spring loads ensure that after releasing the hand lever 20 Lock hinge fittings 5 again automatically and the current setting of Secure the backrest 3.
- An elongated hole 17 'in the unlocking disc 17 causes that with a pivoting movement of the hand lever 20 down the unlocking disc 17 does not take the release bolt 19 with it due to an empty stroke, i.e. the joint fitting 5 remains locked.
- the vehicle seat 1 has one at each of its two rear corners on the seat part 2 rear foot 22, which with the vehicle floor as part of the vehicle structure is locked, for example by means of pawls in the rear foot 22 and bolts in Vehicle floor.
- the rear feet 22 remain in the event of a possible longitudinal displacement the vehicle seat 1 locked to the vehicle floor.
- For the bottom release 24 is on the top Transmission shaft 13 has a disk-shaped driver 26 attached in a rotationally fixed manner.
- a one-armed, first lever 28 is arranged in the driver 26, which rotatably sits on the upper transmission shaft 13 and through an opening 15 'in the connecting cross member 15 protrudes radially.
- the driver 26 has one in parallel to the upper transmission shaft 13 arranged pin 26 ', which in one Slot 28 'of the first lever 28 engages, as shown in Fig. 2.
- the first lever 28 In the locked state of the vehicle seat 1 in its rearmost longitudinal position is the first lever 28 with its free end on the free end of one also one-armed, second lever 30.
- the second lever 30 is non-rotatably on a lower transmission shaft 32, which is between the two rear feet 22 extends and is aligned parallel to the upper transmission shaft 13.
- the lower transmission shaft 32 is operatively connected to not shown Cams, which release a pawl during a swivel movement, the rear Foot 22 locked to the vehicle floor. Therefore, the floor release 24 actuated by a rotation of the first lever 28, which then on the second Lever 30 presses, which in turn rotates the lower transmission shaft 32, the latter then unlocked both rear feet 22 at the same time.
- the first lever 28 is one of the components of the seat part 2, which at a Longitudinal displacement of the vehicle seat 1 are also moved, the lower one Transmission shaft 32 including the second lever 30 to the components of the seat part 2, which not be moved.
- the first lever 28 does not rest on the second lever 30, so that the floor release 24 cannot be actuated.
- the first lever 28 additionally with a 28 "finger pointing backwards and the backrest 3 with a curved about the backrest axis of rotation 3 'and approximately below the same arranged curve segment 33 provided.
- the finger 28 "is on the curve segment 33 at.
- a pivoting movement of the first lever 28 is then blocked. If, on the other hand, the backrest 3 is folded completely forwards, it moves away the curve segment 33 completely from the touch finger 28 ". The bottom release 24 can now by means of the pivoting movement of the first lever 28 be unlocked.
- the vehicle seat 1 is in a package position transferable. To do this, first use a swivel movement of the hand lever 20 upward actuated the backrest release 11 described above, with an idle stroke movement of the pin 26 'within the slot 28' of the first lever 28 and thus the bottom release 24 remains unactuated. Now the backrest 3 folded forward onto the seat part 2. Then through a swivel motion of the hand lever 20 actuated downward the bottom release 24, whereby by the Movement of the elongated holes 17 'relative to the unlocking bolts 19 now unlock the backrest 11 remains inactive. The seat part 2 is then, with the backrest 3 ahead, swung his front feet forward into the package position.
